[PATCH i-g-t 06/10] scripts/xls_to_doc.py: preserve line for found fields

[Mauro Carvalho Chehab]

From: Mauro Carvalho Chehab <mchehab at kernel.org>

By default, the update logic will place new values at the end of
subtests.

Yet, if the field is already at the source file, just update
the value at the line.

Please notice that the logic needs to parse the entire subtest
description, as continuation lines may be present.
